TWO-ROW CULTIVATOR.

Specification of Letters Patent.

' Patented May 4, 1915.

To all whom it may concern:

Be it known that I, Lnwrs E. \VATERMAN,

a citizen of the United States, residing at Rockford, in the countyofWinnebago and State of Illinois, have invented certain new and usefulImprovements in T wo-Row Cul- 'tivators, of which the following is aspecification.

This invention pertains 1n' general to the art of cultivators and hasmore particular reference to riding cultivators intended for use incultivating corn or other crops which f are planted in rows, theembodiment of: my

'invention,,f;hown for illustration in the present instance, beingadapted to simultaneously cultivate two rows, although it will beobvious as the invention is better understood that the principles of theinvention might be incorporated 1n either a single or multirowcultivator.

One of the primary objects of this invention is to provide a cultivatorwhich will be light and at the same time strong and durable and whichwill be so flexible and easy to manipulate that it will readily respondto guidin movements of the operator, and can e shi ted and controlledwith a minimum expenditure of energy.

Morespecifically my invention has for one of its ob ects the provisionof a cultivator embodying improved means for shifting all of the beamslaterally and simultaneously angling the wheels in a correspondingdirection. I

Another-object is to provide simple and efficient mechanism whereby thebeams ma be individually adjusted to cultivate at various depths and maybe simultaneously raised or lowered by the simple manipulation'of asirigle manually controlled lever.

further object'is to provide novel and improvedmechanism for adjustingthe beams laterallyto vary the distance between the beams of each pairand forfmaintaining the beams in their adjusted positions.

Additional objects and many of the inherent advantages of the inventionwill be readily apparent as the. same becomes better understood byreference to the following in connection description when consideredwith the accompanying drawings.

Referring tothe drawings Figure 1' is aplan view of a cultivatorembodying my Fig. 2 is'a fragmentary sectional- View on the line 2-2 ofFig. 1; Fig. 3 is a transverse sectional view on the line 3-3 of Fig. 2;Fig. 4 is a fragmentary sectional view on the line 4-4 of Fig. 1; Figs.5 and 6 are transverse sectional views taken on the lines 5-5 and 6- 6respectively of Fig. 1; Fig. 7 is a fragmentary elevation partially insection of the mechanism for adjusting the beams laterally with respectto each other, and Fig. 8 is a fragmentary sectional view taken on theline 8-8 of Fig. 1.

From an inspection of the drawings it will be apparent that the mainframe of the machine comprises a transverse member 9 to which two pairsof shaped frame members 11 are rigidly bolted at their rear inturnedends, the outer ends of each pair of members 11 being bolted orotherwise rigidly secured to the opposite facesof the rear ends of thepoles or tongues 12, to which the horses are attached. I l.

To each side of the-frame thus formed I have fixedly attached a standardmember or bracket 13 shaped to provide "a vertically disposed sleeve orjournal 14 in which the vertical portion 15 of an L-shaped axle memheris pivotally mounted, the horizontal portion 16 of the axle membersforming the axle'members is rigidly mounted an arm 18 which extendsforwardly from its respective vertical portion 15, the arms 18 beingdis-; 1'

posed parallel with eachother and with the wheels.

1 and 2, it will beobserved that the forward extremities of the arms 18are each forked to accommodate a sleeve, 19 which is pivot-' allyconnected with its respective arm, the pivotal connection being"effected by op; positely projecting-studs 21 formed on the sleeve. andseated in corresponding bearingsv formed in the prongs of the member 18.The arms 18 and, consequently, the wheels 17 are maintained in parallelrelation by atransversely disposed shaft 22 journaled in Referring nowmore particularly to Figs.

each sleeve 19 and maintained against lon gitudinal movement withrespect to these sleeves by means of pairs of pins 23 inserted throughthe shaft on opposite sides of each sleeve. It will be obviousthat-longitudinal movement of the shaft will simultaneously v will nowbe described,-and since all of the angle bothof the wheels about theirvertical grespectively (Fig. 1), one for each of the cultivator beams,are each loosely mounted upon the shaft 22 and provided with adownwardly disposed socket 28 in which the upper end of a post 29 isrigidly secured. The posts are therefore suspended from and supported bythe-shaft 22. The cultivator beams, designated by reference character31, are each equipped at their forward ends with avertically disposedsleeve 32 slidably mounted. upon one of tlieposts 29 so that the beamsmaybe moved vertically on the post to raise and lower the shovels orother cultivating tools (not shown) carried by the beams. Since thesleeves 32 are rigidly attached to the beams 31 it will be obvious thatthe sleeves will maintain the beams in substantially horizontalposition, as shown in Fig. 5.j In order to prevent the posts' fromswinging about the shaft 22 Iv have provided a series of braces 33, eachof which is bolted at its lower end to a post 29 and is attached at itsupper end to a transversely disposed bar or angle member 3a bolted orotherwise fixedly secured to the poles 12. These braces hold the postssubstantially rigidly in a vertical position, thereby insuring a horizomtal position of the beams 31.

The beams are adjusted vertically on the posts129 and are held inadjusted position by individual adjusting mechanisms which mechanismsare substantially identical :1 detailed description of one will sufficefor an understanding if the invention. 40

Referring, now to Figsll, 2, 3 and 5, it Will be observed that a sectormember 35 is mounted upon the shaft adjacent to each sleeve 27 and isprovided with an overhanging portion 36 which engages with a flange 37formed on the sleeve 27 so that the sleeve portion 38'of the sectormember is held against longitudinal movement relatively to the sleeve27. The sleeve 38 and, consequently, the sector member are maintainedagainst r0; tative movement relatively to the shaft 22 by means of a pin39 extending through the shaft into oppositely disposed grooves ll and42 formed on the interior of sleeve 38,

as shown in Figs. 2 and 3. A hand lever 413 is pivotally' mounted'iipona bolt 44 to each sector member 35, the longer arm of the lever beingequipped with a manually con-' trolled latch 45,.of any preferredconstruction, adapted to engage with the notches 4:6 in the sectormember to hold said lever in adjusted position. "The shorter arm 47 ofthe le ee is connected with the sleeve '32 by a eonnecting 'r0d48 sothat said sleeve and the (team-carried thereby' are I raised or lowene'd "as the lever is moved inone direction 1,137,e3s I or the otheraboutits pivot. Since each of the beams is connected with a similaradjusting lever it will be obvious that the beams may be individuallyraised or lowered and retainedin adjusted position by means of theindividual adjusting levers described.

In practice the beams are set to the required depth by means of theindividual ad 'ju sting levers and are then left in this.ad

justed position while theraising and lbwering of all of the beams fromoperative to inoperative position and vice versa are accompllshed bymeans of a single l aising and lowering lever, which will now bedescribed.

Referring to Figs. 1, 4. and s, a will be observed that a lever a9 iscarried by a base 51 which in turn is immovably secured to the shaft 22by a bolt 52. A cotiperating sector member 53 is formed to provide asleeve 54 which loosely embraces the shaft 52 but is held againstrotation iwith said shaft by means of rearwardly extending prongs 55which slidi-ngly engage with the top and bottom of the transverse framemember 9. The lever 4l9 is equipped with a manually operable latch 56adapted to engage in notches 57 formed in the sector member 53, wherebysaid lever is retained in adjusted position. Assuming that the le- "ver49 is in the position shown in Fig. 8 the beams will be inloweredposition for the reason that the sector members 35 and levers 4-3will be positioned as shown in Fig.

5. In order to raise the beams the lever 49' is swung. from the positionshown in Figs.

5 and 8 rearwardly or in a counter-clockwise direction, thereby,rotating the shaft 22 and the sector members 35 and levers 43 carriedthereby to elevate the extremity of the le- -ver arms l'i and therebylift the beams. It will be manifest therefore that the beams may beraised and. lowered individually by the levers l3, and raised andlowered collectively by the lever 4:9. I r j c For the purpose ofadjusting the beams longitudinally of the shaft 22 to position the beamsof each pair closer together or farther apart I have provided mechanism,best shown in Figs. 1, 6 and 7, which com prises a sector member 58loosely sleeved on the shaft 22, as shownin Fig. 6, but held againstlongitudinal movement relative to the shaft by means of pins59-projecting through the shaftat each end of the sleeve. The sectormember is held against rotary movement with the shaft by a-pair of rigidgage the bottom and top' respectively of the frame member 9.An'adjusting lever 63 is pivoted upon a stud fil-projectingjupwardlyfrom the sector sleeve and is equipped with amanually'controlled latch65, of any approved construction, which is adapted to engage in thenotches 66 of the sector memfingers 61 and 62 positione'd'to slidinglyen her to hold the lever in adjusted position. Th: sleeves and 27 arerespectively connected with the forward extremity of lever I 63 by links67 and 68 while sleeves 2 and 26 are connected with the lever at theopposite side of its fulcrum by similar links 69 and 71. Viewing Fig. 1it will be obvious that when the rear end of lever 63 is swung to theright the individual beams of each pair will be moved apart and whensaid lever is moved in the opposite direction the beams of each pairwill be moved closer together. The beams are retained in their adjustedposition by the lever 63 through interlocking engagement of the latch 65with the sector member 58. Since the sector member 58 and the lever 63are carried by the shaft 22 and are held against movement longitudinallyof the shaft it will be obvious that longitudinal movements of the shaftto angle the wheels will shift the beams laterally all together withoutdisturbing or affecting the spacing of the beams with relation to eachother.

The shaft 22 is moved longitudinally to angle the wheels and shift thebeams by means of a lever 7 3 pivoted in a bracket 7% fixed on the mainframe member 9, said lever be ing pivotally connected at 7 5 with thesleeve of the sector member 58 and being provided at its oppesitedownturned end with a crossbar 76 equipped with stirrups 77. The seategally about its pivot in the bracket 7 8, upon which the operator sits,is carried by a pair of bars 79 bolted at their forward ends to theinnermembers 11 and restin upon the} frame member 9. The rear en ofshifting lever 73 is supported from the seat bars by a link 81 hookedover the bolt 82 extending between the seat bars. The seat is rigid withthe main frame and when the operator pushes laterally with his feet in,the stirrups 77 the lever 73 is swung lat- 4 to ereby move the shaft 22longitudinally, which movement, asihas been previously described, shiftsthe beams laterally and simultaneously angles the wheels. It is believedthat my invention and its mode of operation will be readily understoodfrom the foregoing without further description, and sincevarious othermodified forms may be made without departing from the'spirit of thisinvention I do not Wish to confine myself to the exact embodiment shownand described, but wish to claim all such modified forms as would comeproperly within the general scope of the invention as set forth in thefollowing claims.
